Before we dive in, remember that successful trellis gardening involves choosing plants that complement your trellis design, considering their mature size, and ensuring they're well-supported. Now, let's climb into the world of beautiful, vertical greenery!

Woody Vines for Structural Support

Woody vines are robust, long-lived plants that provide excellent structural support for your trellis. They grow slowly but form a strong, permanent framework for your vertical garden.

These plants are perfect for creating living screens or supporting heavier plants in your trellis design.

Clematis (Clematis spp.)

Clematis is a large genus of woody vines, offering a variety of flower colors, shapes, and blooming times. Many cultivars are hardy in Zone 7, such as the early-blooming 'Jackmanii' with its deep purple flowers and the late-blooming 'Nelly Moser' with its large, white blooms edged in pink.

Most clematis vines require minimal pruning and can be trained to grow on trellises or through other plants. They prefer partial shade and consistent moisture.

Wisteria (Wisteria spp.)

Wisteria is a stunning, fast-growing vine that produces beautiful, fragrant purple or white flowers in late spring. The Japanese wisteria (W. floribunda) and American wisteria (W. frutescens) are both hardy in Zone 7.

Wisteria requires strong support, as it can become quite heavy. It's essential to prune it annually to control its size and encourage flower production. Wisteria is also a nitrogen-fixing plant, improving soil fertility over time.

These plants are perfect for adding instant impact to your trellis and can be interchanged for variety year after year.
